Myonuclei acquired by overload exercise precede hypertrophy and are not lost on detraining

JC Bruusgaard, IB Johansen, IM Egner… - Proceedings of the …, 2010‏ - pnas.org
Effects of previous strength training can be long-lived, even after prolonged subsequent
inactivity, and retraining is facilitated by a previous training episode. Traditionally, such …

Cellular and molecular mechanisms underlying age-related skeletal muscle wasting and weakness

JG Ryall, JD Schertzer, GS Lynch - Biogerontology, 2008‏ - Springer
Some of the most serious consequences of ageing are its effects on skeletal muscle. The
term 'sarcopenia'describes the slow but progressive loss of muscle mass with advancing …

Muscle memory and a new cellular model for muscle atrophy and hypertrophy

K Gundersen - Journal of Experimental Biology, 2016‏ - journals.biologists.com
Memory is a process in which information is encoded, stored, and retrieved. For vertebrates,
the modern view has been that it occurs only in the brain. This review describes a cellular …

Apoptotic adaptations from exercise training in skeletal and cardiac muscles

PM Siu, RW Bryner, JK Martyn, SE Alway - The FASEB journal, 2004‏ - Wiley Online Library
The effect of exercise on apoptosis in postmitotic tissues is not known. In this study, we

JS Kim, JM Wilson, SR Lee - The Journal of nutritional biochemistry, 2010‏ - Elsevier
Sarcopenia, the age-related loss of muscle mass and strength, is a fundamental cause of
frailty, functional decline and disability. In the year 2000, $18.5 billion in health care costs …

Evidence that satellite cell decrement contributes to preferential decline in nuclear number from large fibres during murine age-related muscle atrophy

AS Brack, H Bildsoe, SM Hughes - Journal of cell science, 2005‏ - journals.biologists.com
Skeletal muscle fibres are multinucleate syncitial cells that change size during adult life
depending on functional demand. The relative contribution of change in nuclear number …
